PB,
I am a big fan of the Mosin-Nagant. An M39 can rank right up there with a Swiss K31 or a Swede Mauser for accuracy.
The '41' marked rifle is cool. These are thought to be Winter War captured pieces pressed into service by the Finns. If that is the case, it likely belonged to one of the one million casualties the Russians suffered in that engagement. The Finns taught the Russians a lesson. The Russians found out that their leadership was terrible (a result of the Stalin Purges) and their tactics woeful.
The subsequent Russian military reforms were ongoing when Barbarosa appeared on the Steppes. The Russians learned and as a result, the Germans paid a terrible price. But then, so did the Russians...some 20 million dead in the Great Patriotic War against the Facists.
I dig these old battle rifles. They are a relic of momentous times.
Regards,
Mahatma
